What is CVE-2026-100622?

Capgo App through version 12.129.0 contains a vulnerability that allows unauthenticated users to exploit cached bundle artifacts. This occurs when the application fails to properly verify the deletion status of these bundles at the public file read endpoint. As a result, attackers can manipulate cached URLs to download previously deleted bundles. Additionally, this vulnerability can be exploited to restore deleted objects into R2 storage upon cache hits, posing a significant threat to data integrity and security.
